Create a Contact Group
If you want to text several friends at once or hear a different ringtone when work calls versus family, MIUI needs your contacts sorted into groups first. Without a group, every message goes out individually and every caller sounds the same. Xiaomi handles this through a labeling feature inside the Contacts app that most people never notice.
Mirror Navigation Bar Buttons
If the back button and recent apps button feel like they are on the wrong side of the navigation bar, your Xiaomi phone likely has the default three-button layout active. Left-handed users especially notice this, since reaching for the back key on the left edge feels unnatural. A hidden toggle lets you flip the order of these two buttons without changing anything else on the home button.
Rename Face Data
If you have saved more than one face profile on your Xiaomi phone, for example a regular look and one with glasses, every entry shows up under the same generic label in the Face unlock settings. Without a custom name it is hard to tell which profile matches which appearance, especially when you only want to manage or delete one of them.
Manage Synced Gallery Albums
When Xiaomi Cloud sync is turned on, Gallery uploads every new photo and video automatically, including albums you would rather keep local. That fills up your cloud storage fast and makes it hard to tell which albums are actually being backed up. Instead of switching cloud backup off completely, you can review and adjust the sync status for each album on its own.
Auto-Update Download Settings
If your Xiaomi phone keeps downloading system updates in the background without asking, it can eat into your data plan or fill up storage at the worst moment. On the other hand, if updates never download automatically, you might miss important security patches for weeks. This behavior is controlled by a single toggle buried inside the MIUI version screen, separate from the mobile data download option next to it.
Delete a Conversation
Deleting a text thread one message at a time on a Xiaomi phone takes forever once a conversation has piled up over months. Long threads eat into storage and clutter your inbox, and most people never notice the shortcut MIUI offers for removing a whole conversation at once. Once you confirm the deletion, the messages are gone for good, so it helps to know exactly where to tap first.
Send a Group Message (SMS/MMS)
When you try to text several people at once on a Xiaomi phone, it is not always clear whether picking multiple names in Contacts actually creates a real group thread. MIUI also switches silently between SMS and MMS depending on whether photos or long text are attached, so replies can end up scattered across separate one-on-one chats instead of a single conversation.
Turn MMS Read Receipts On or Off
If contacts can see the moment they read your MMS messages, or you cannot tell whether your own texts got opened, the read receipt option is likely misconfigured on your Xiaomi phone. This setting works separately from standard SMS delivery reports and needs its own toggle inside the messaging app. On Dual SIM devices, each SIM line can carry a different receipt setting, which often explains why the behavior seems inconsistent between conversations.
Turn On/Off Ad Blocker in Mi Browser
If ads keep interrupting your browsing or pages suddenly feel slower to load, the built-in ad blocker in Mi Browser is likely the reason. Xiaomi ships this filter active by default, similar to the pop-up blocker, and it can be switched on or off depending on how you want pages to render. Turning it off removes the filtering step but may bring back more banners and auto-play video ads.
Turn On/Off Ascending Alarm Volume
If your Xiaomi alarm starts at full volume and jolts you awake instead of easing you into the morning, the ascending volume option is likely switched off. Some users prefer the opposite: a gentle ramp-up feels too quiet to wake them at all. Either way, this sits in a separate alarm setting that many people never notice.
Automatic App Updates Settings
If your Xiaomi phone only refreshes apps once it finds a Wi-Fi network, updates can lag behind for days when you are mostly on mobile data. This behavior comes from the Play Store auto-update setting, which defaults to Wi-Fi only on most Xiaomi devices. You can switch it to update over any network or turn automatic updates off completely.
Set the Action for When Your Data Plan Runs Out
If your mobile data suddenly stops working before the month is over, MIUI may already be cutting it off automatically once you hit your set limit. Some people only want a heads-up instead of losing their connection outright, but that only works if the right action is selected in the data usage settings. Without checking this setting, you can end up with dead mobile data at the worst possible moment.
Add Apps to a Folder on the Home Screen
Dragging one app at a time into a folder gets tedious once your home screen fills up with dozens of icons. Xiaomi phones running MIUI let you group several apps into a single folder in one move instead of repeating the drag-and-drop for each icon. If you only know the old hold-and-drag method, sorting a full app drawer can take much longer than it should.
Find a Word on a Webpage
Scrolling through a long article on your phone just to spot one specific term wastes time, especially when the page has no search box of its own. Mi Browser hides a page search tool that jumps straight to every match of a keyword. Without it, you are stuck pinching, zooming and reading line by line to find what you need.
Turn Emoji Suggestions On or Off
If your Xiaomi keyboard keeps popping up matching emoji while you type and it gets in the way, or you want those suggestions but they never show up, the setting behind this is Show emoji suggestions inside the keyboard's text correction options. Many users only stumble onto this toggle while browsing keyboard settings and are not sure what it actually changes. Depending on how it is set, MIUI either offers a matching emoji for recognized words or stays completely quiet.
Check Battery Usage Stats per App
If your Xiaomi phone drains faster than usual, it helps to see which app or function is actually responsible before you start disabling things at random. MIUI keeps a detailed breakdown of battery usage, separating screen time, standby drain, and individual apps, but this overview sits a few taps deep in the settings. Without checking these numbers, you're only guessing at what's eating your charge.
App Download Preference (Play Store)
If apps on your Xiaomi phone start downloading over mobile data even while connected to Wi-Fi, the Play Store's download preference is likely set to Over any network. This setting decides whether new app installs and updates use any connection, Wi-Fi only, or ask before each download. Getting it wrong quickly eats into a limited monthly data plan.
Flip to Silence Ringer: Turn On or Off
If your Xiaomi phone keeps ringing loudly even when you quickly flip it face-down during a call, the Flip to silence ringer feature is likely turned off. When active, flipping the device mutes the ringtone, stops the vibration and turns off the notification light instantly. The caller still hears it ringing though - the call is not rejected or sent to voicemail.
Delete a Contact
Contacts opened from Calls or Messages on a Xiaomi phone are the same entries stored in the Contacts app, so removing one wipes it out everywhere at once. Syncing with your Google Account does not stop the local delete from going through, and once it is confirmed there is no built-in way to bring the entry back.
Enable or Disable Captions for Supported Apps
When captions do not appear during playback, or they show up in a style that is hard to read against light backgrounds, the caption settings on your Xiaomi phone are usually the reason. This affects apps that hook into the system-wide caption feature, not just the video player itself. Size, color, and background of the caption text can all be adjusted separately from whether captions are shown at all.
Show or Hide Declined Calendar Events
Declined meeting invites disappear from the Xiaomi Calendar app by default, so you cannot see which appointments you turned down or check past responses. This happens because the toggle that controls declined-event visibility is switched off in the calendar settings. Depending on how your Google account syncs, hidden entries can also make your event history look incomplete.
Set Up Unlock with Bluetooth Device
If your Xiaomi phone stays locked even though your paired Bluetooth accessory is nearby, the Unlock with Bluetooth device feature is probably still off. Once active, the phone unlocks automatically near that device and stays unlocked as long as the connection holds. This only works with Xiaomi's own Bluetooth accessories, not with third-party headphones or wearables.
Turn Global Icon Animations On or Off
If third-party app icons on your Xiaomi phone bounce or pulse every time you tap them, a system-wide animation setting is running in the background. Some people like the extra feedback, others find it distracting or feel it slows down the home screen. This setting controls the effect for all installed apps at once, not for a single icon.
Camera Delay-Timer
If your Xiaomi camera fires the shutter the instant you tap the button, group photos or selfies often turn out blurry or catch you mid-pose. MIUI has a built-in delay-timer for exactly this situation, but it sits hidden inside the camera menu instead of the main shooting screen. Without it, you only get a split second to get into position before the shot is taken.
